Raw hunger or thirst usually draws people to buy snacks from vending machines. Healthy options, calorie counts and reminders help consumers make good-sense decisions when they slip in coins or a credit card, according to research by a working group organized under UC's Global Food Initiative and led by the UC Nutrition Policy Institute.
The working group set out to develop guidelines for food service providers at all 10 UC campuses and other UC facilities in stocking and promoting healthy options in their vending machines. They also created a toolkit with step-by-step guidance in making the switch, including everything from early meetings with students, food service and vendors to anticipating and preparing for barriers to implementation.
As part of the project, the Nutrition Policy Institute evaluated data from six UC campuses that show healthy vending options are growing in popularity, which eases concerns about a potential reduction in profit by making vending healthier.
“In 2005, California began introducing policies limiting junk food in vending machines and student stores on K-12 campuses,” said Janice Kao, a researcher at the Nutrition Policy Institute and chair of the working group. “Today's college students are used to having healthy snack options in schools. Customer resistance that some vendors talk about isn't necessarily the case anymore.”
Two UC campuses – UCLA and UC San Francisco – have been early adopters in making healthy vending machine choices available. According to the evaluation, the two locations achieved the goal of having 70% of their beverage vending products fit the “healthy” description. Other UC campuses are working on adding healthy options – with a wide variation in implementation and definition of “healthy.”
The Global Food Initiative working group recommends a higher standard for “healthy” snacks than some campuses and vendors. The key difference is the decision that an item can only be considered “healthy” if the first ingredient is a fruit, vegetable, low-fat dairy, protein or whole grain.
“This guideline means some granola bars cannot be considered a healthy snack,” Kao said.
Even so, the evaluation results showed improvement in the sales of healthy products.
“Campuses that have actively worked on healthy vending saw greater sales of healthy snacks and drinks,” Kao said. “We want to learn from those experiences and develop systemwide standards to provide consistency. With everyone following the same guidelines, there is potential to take advantage of systemwide food procurement economies of scale and contribute to meeting UC's sustainability goals.”
The NPI evaluation compared the greenhouse gas emissions associated with traditional vending and healthy vending. A dramatic difference emerged when comparing candy bar ingredients and healthy snack bar ingredients. Greenhouse gas emissions of candy bar ingredients were estimated to be more than twice as high as healthy snack bar ingredients.
Shoppers purchasing fruits and vegetables in stores located in low-income neighborhoods in California may pay more for those fruits and vegetables than shoppers in other neighborhoods, according to a study that examined prices in a large sample of stores throughout the state.
Published online in March 2018 in the journal Public Health Nutrition, the study, conducted by researchers at UC's Nutrition Policy Institute, involved more than 200 large grocery stores, 600 small markets, and 600 convenience stores in 225 low-income neighborhoods (where at least half of the population was at or below 185 percent of the Federal Poverty Level) and compared observed prices to purchased price data from chain grocery stores in the same counties during the same months.
The study found that produce prices for the items examined (apples, bananas, oranges, carrots and tomatoes) were higher in stores in low-income neighborhoods than the average prices of those items sold in stores in the same counties during the same month. Fruits and vegetables for sale in convenience stores in low-income neighborhoods were significantly more expensive than those for sale in small markets or large grocery stores. Yet even in large grocery stores the study found prices in the low-income neighborhoods to be higher than average county grocery store prices during the same month.
“Americans eat too few fruits and vegetables to support optimal health, and we know that dietary disparities among socioeconomic groups are increasing,” said study author Wendi Gosliner. “This study suggests that one important issue may be fruit and vegetable prices — not just that calorie-per-calorie fruits and vegetables are more expensive than many unhealthy foods, but also that there are equity issues in terms of relative prices in neighborhoods where lower-income Californians live.”
Additionally, the study examined the quality and availability of fruits and vegetables in stores and found that while less than half of convenience stores (41 percent) sold fresh produce, even fewer (1 in 5) sold a wide variety of fruits or vegetables, and few of the items that were for sale were rated by trained observers to be high quality (25 percent for fruits and 14 percent for vegetables).
“This study suggests that convenience stores in low-income neighborhoods currently fail to provide access to high-quality, competitively priced fresh fruits and vegetables," said Pat Crawford, nutrition expert and study author. “A healthy diet can prevent disease and reduce health care costs in the state. States need to explore new ways to help ensure that families, particularly those living in low-income neighborhoods where convenience stores are the only food retailers, have access to healthy, high-quality foods that are affordable,” Crawford added.
The study also found that convenience stores participating in federal food programs (the Supplemental Nutrition Assistance Program [SNAP] and/or the Supplemental Nutrition Program for Women, Infants, and Children [WIC]) were more likely to sell fresh produce and to offer higher quality and a wider variety of fruits and vegetables than stores not participating in either program.
The study was conducted under contract with the California Department of Public Health. Funding is from USDA SNAP. USDA is an equal opportunity provider and employer.
